RESUMO
Purpose: The aim of present study was to assess the frequency, severity, and distribution of developmental defects of tooth enamel and correlate the etiology with the type of defect in 11-13-year-old Indian children. Materials and methods: The present study included examination of permanent maxillary incisors in 500 children in the age-group of 11-13 years to examine the occurrence of distribution of developmental defects of tooth enamel. Materials and methods: Only the buccal surface of four permanent maxillary incisors was examined for enamel defects using modified developmental defects of enamel (DDE) index by Clarkson which recognized three basic types of enamel defects; namely demarcated opacities, diffuse opacities, and hyploplsia. Personnel details, dental history which included dental infection, extraction, trauma, lifetime fluoride, fluoride in water, and medical history were also recorded. Data was coded and analyzed for distribution of developmental defects of tooth enamel by tooth type and gender using Statistical Package for the Social Sciences. Result: Out of 500, 114 (22.8%) children showed defective enamel in permanent maxillary incisors. Of all enamel defects, diffuse opacities were most prevalent with 48.25% occurrence followed by demarcated opacities 38.5%, hypoplasia 10.52%, and any other defects 1.75%. No significant difference was observed in males and females for the occurrence of developmental enamel defects. The occurrence of dental enamel defect significantly correlated with dental history as well as with medical history (Chi-squared statistical test, p-value = 0.001**). Conclusion: (1) High fluoride in water accounts for most prevalent diffuse opacity. (2) Demarcated opacities are associated mainly with positive dental history. (3) Hypoplasia of incisors was found to be least prevalent associated with trauma, periapical infections. How to cite this article: Sheoran N, Garg S, Dhindsa A, et al.

RESUMO
To improve consumer engagement and satisfaction, online news services employ strategies for personalizing and recommending articles to their users based on their interests. In addition to news agencies' own digital platforms, they also leverage social media to reach out to a broad user base. These engagement efforts are often disconnected with each other, but present a compelling opportunity to incorporate engagement data from social media to inform their digital news platform and vice-versa, leading to a more personalized experience for users. While this idea seems intuitive, there are several challenges due to the disparate nature of the two sources. In this paper, we propose a model to build a generalized graph of news articles and tweets that can be used for different downstream tasks such as identifying sentiment, trending topics, and misinformation, as well as sharing relevant articles on social media in a timely fashion. We evaluate our framework on a downstream task of identifying related pairs of news articles and tweets with promising results. The content unification problem addressed by our model is not unique to the domain of news, and thus can be applicable to other problems linking different content platforms.
RESUMO
The study was conducted to investigate the extent to which students of two dental schools in northern India make use of internet during their undergraduate course and to assess their attitude towards the internet in general. All undergraduate students were assessed using a specially designed, self-administered questionnaire. Overall, 470 (88.84%) students used the internet. Among the internet users, only 207 (44%) accessed it for academic purposes. Also, 356 (75.7%) found information about dentistry easily accessible, whereas 114 (24.3%) reported difficulty in doing so. The study showed that a good number of Indian dental students are using internet, but they are lagging behind their counterparts in the western world.
